In this paper we describe control challenges related to operation of oil wells equipped with Electric Submersible Pumps (ESP) and formalize them in a control problem setting in the language of control system engineers. Then we present a simple dynamic model of an oil well equipped with ESP. This model can be used for controller development. To solve this(More)
Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a eld with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the eld such that the total production of oil from the eld is maximized. This paper describes a(More)
The need for early fault detection and effective maintenance operations in the industry makes us think about developing tools that that can handle the uncertainty of the processes and improve the maintenance scheduling. Among other decision support tools, Bayesian Networks (BN) is a method that can handle the uncertainty in industrial processes. If we add(More)
